When you steam potatoes and then store them in the refrigerator, the water content in the potatoes may change. Here's what typically happens:

1. Initial Moisture Loss: Steaming potatoes involves cooking them with steam, which can lead to some initial moisture loss as the potatoes cook. This loss of moisture contributes to the softening of the potatoes during cooking.
2. Reabsorption of Moisture: After steaming, when you store the potatoes in the refrigerator, they can reabsorb some of the moisture from the surrounding environment, which may include steam condensing on the surface as they cool.
3. Texture Changes: As the potatoes cool and sit in the refrigerator, they might undergo some textural changes. They could become slightly firmer as they reabsorb moisture, especially on the surface. However, the interior of the potato may remain relatively stable.
4. Moisture Loss Over Time: Over time, stored potatoes can continue to lose moisture, especially if they are not stored in an airtight container. This can lead to the potatoes becoming drier and potentially developing a less desirable texture.

To best maintain the quality and moisture content of steamed potatoes when storing them in the refrigerator:

• Allow the steamed potatoes to cool to room temperature before refrigerating to minimize condensation.
• Store them in an airtight container to prevent moisture loss or gain from the surrounding environment.
• If you plan to use the potatoes in dishes that require them to be reheated, you can reheat them in a way that adds moisture, such as by microwaving with a damp paper towel or by incorporating them into recipes with sauces or liquids.

Overall, steamed potatoes can be stored in the refrigerator, but their moisture content may change somewhat due to the factors mentioned above. Proper storage and handling can help minimize these changes and maintain their quality.
